m3ta-chironandClaude Fable 5.1 1b971bc3f6 fix: Windows daemon survives session jobs; quieter wrap note; correct mute error
Verified on a Windows 11 VM over WinRM: doctor, SAPI synthesis, Edge,
oto/WASAPI playback, autostart, mute file, wrap exit codes, doctor --probe
and toast mode all work. Three findings fixed:

- The autostarted daemon died with the WinRM shell: Windows session hosts
  (WinRM, SSH, CI runners) put children into a job object that is
  terminated with the session. Spawn now starts the daemon with
  CREATE_BREAKAWAY_FROM_JOB first and falls back to a start without it when
  the job forbids breakaway. Confirmed: the daemon now outlives the WinRM
  shell and `talk daemon stop` still ends it.
- `talk mute` without a daemon printed "daemon call failed (<nil>)": the
  outer err was reported instead of the call's. Now "no daemon (<reason>);
  writing the mute file directly".
- `talk wrap` printed "command did not exit cleanly" for every non-zero
  exit code. The note is now reserved for commands that produced no exit
  code of their own (not found, signal); a plain failure is carried by the
  announcement and the exit code alone.
